Nozznn Specification of Letters Patent.

Patented June '28, 1921.

Application filed August 15, 1918. Serial No. 249,928.

panying drawings, and tocharacters of reference marked thereon, whichform a part of this specification.

This invention has reference, generally, to improvements in nozzles foruse in connection with hose; and, the present invention relates, moreparticularly, to a novel construction of nozzles for attachment to ahose for throwing a stream of water, and combining with the nozzle meansattached thereto in such a manner that a vacuum and a suction will beproduced with the nozzle, and that thereby a fluid may be drawn into thenozzle and caused to intermix with the water prior to being forced fromthe discharging end of the nozzle.

The present invention, therefore, has for its principal object toprovide a nozzle of the general character and novel arrangement andconstruction of the various devices and 'parts thereof, whereby thenozzle-may be used for varlous purposes; such as disinfecting andfertilizing purposes, for fighting fires in combining chemicals with astream of water, for destroying germicides, washing purposes, destroyingacid and other obnoxious fumes, and in some instances being aplicable-in condensing exhaust steam.

ther objects of the present invention not at this time more particularlyenumerated will be fully understood from the following detaileddescription of the present invention.

With the various objects of the present invention in View, the saidginvention consists, primarily, in the novel nozzle hereinafter morefully set forth; and, the invention consists, furthermore, in the novelarrangements and combinations of the several devices and parts, as wellas in the details of'the construction of the said parts, all of whichwill be more fully described in the following specification, and'thenfinally embodied in the clauses of the claim which are appended to andwhich form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of a nozzle made according to andembodying the principles of the present invention; and Fig. 2 is alongitudinal and vertical section of the same.

, Fig. 3 is an end view of the nozzle, looking toward the dischargingend, of the same; and Fig. 4 is a transverse vertical section of thenozzle, said section being taken on line 4.4: in said Fig. 2, looking inthe direction of the arrows in said figure.

Similar characters of reference are employed in all of the above saiddescribed views, to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicatesthe complete nozzle, showing one embodiment of the principles of thepresent invention, the same comprising a main tubular member or element2 which is internally screw-threaded,

at its respective end-portions, as at 3 and 4. Suitably screwed into thescrew-threaded end 3 of the said member or element 2 is asuitably-formed coupling, as 5, preferably provided with an annularflange 6, or the like, between which and the end of said member orelement 2 theremay be disposed a suitable washer, as.7, to preventleakage at that point, as will be evident. Suitably connected with thesaid coupling 5, upon the opposite side of thefiange 6, in any desiredmanner, is the end-portion of a hose 8, substantially as shown in Figs.1 and 2 of the drawings. I

, Suitably. screwed into the screw=threaded end 4 of the said member orelement 2, is the screw-threaded end-portion 10 of another tubularmember or element, as 9, the said member or element 9 being preferablyformed with an annular off-set or-shoulder, as 11, and disposed betweenthe said offset or shoulder and the end of said member or element 2there may be another washer, as 12, of any suitable material, and toprevent leakage between the connected members or elements 2 and 9, aswill be clearly evident from an inspection of said Fi .2 of thedrawings. Upon its opposite en -portion or dischargin end, the saidmember .or element 9 is pre erably provided the member or element 9 byscrewing it' thereon, as indicated at 15 in said Fig. 2. Thesprayer-member or cap may, however, be otherwise secured in its mountedposition upon the end of the member or element 9, as will be clearlyunderstood. As.

shown, the main portion of the said sprayermember or cap is preferablyconcaved as at 16, and'is provided with a multiplicity of sprayer ordischarging perforations 17 which are preferably suitably disposed insuch a manner so that the discharge water, or the. like will pass fromthe nozzle-end, in the direction of the arrows at indicated in said Fig.2. The central portion of the.

provided with an opening 21 in which is' fitted the lower portion of atube 22, said tube being suitably bent in the manner of an elbow, thebent portion 23 of said tube extending into and terminating within theend-portion 20 of the tube 19.

Upon its free end-portion, the bent portion 23 of the tube 22 issuitably fitted with a ca 24 which has a perforation, as 25, forming anoutlet for the purposes toloe presently described. The lower end-portionof the tube 22 projects from said opening 21 and is externallyscrew-threaded, as at 26, for screwing -in position thereon of a tubularfitting 27, over which may be secured the end of a piece of flexibletubing, as 28, forming a suction through which a disinfecting medium, achemical, fumes, or the like are adapted to be sucked and conveyed intoand through the tubes 22 and 19, when a stream of water is permitted toflow from the tubing or hose 8 into and through the nozzle 1. I

Having in the foregoing described the general construction of thenozzle, I will now'briefly describe its use as a vacuum siphon 'fordisinfecting and fertilizing purposes, for use as a fire-extinguishingmeans, for ridding buildings, etc., of acid and other obnoxious fumes,or for condensing exhaust steam. R v

Whennsed for disinfecting, fertilizing, or fire purposes, the free endof the flexible tubin 28 is connected witha reservoir-or tank in whichthe proper fluid or mixture is contained, and the water through the hose8 1s turned into the nozzle. Immediately the Water will pass through thespace 29 formed by the'concentrically.

disposed tubular member or element 9 and the tube 19, the water passingthrough the perforations 17 in the direction of the arrows :0. At thesame time, some of the water passes into and through the tube 19 aroundand about the tube 22, thus causing a vacuum at the perforated cap 24,whereby the disinfecting, or other mixture used, is drawn up into thetubing 28 and by suction caused to pass through the tube 22 and from theerforated cap 24, being thoroughly intermixed Within the tube 19 withthe water passing through the latter tube. At the discharge-end of themain tubular element or member 9 increased suc tion is produced so thatat this point a most efficient mixture of the fluid coming through thetube 19 will be made with the water or fluid coming through the tube 9..

When the nozzle is to be used for the purposes of ridding buildings,tanks, and the like, of acid or other obnoxious fumes, the tubing 28 issimply led into such building or suitably connected with the tank, and,when the water is passed into and from the nozzle, the objectionablefumes or gases are withdrawn in the manner hereinbefore described. In alike manner, the tubing 28 may be connected with a tank, or the like,into which exhaust steam is collected, the exhaust steam being Withdrawnin the manner hereinabove stated, and condensed with the supply of waterpassing from the nozzle, to be suitably collected for future use.

While I consider the arrangement and combination of the devices andparts as illustrated in the accompanying drawings, as the best forproducing a most efiiciently operating nozzle, still I am aware thatsome changes may be made in'the general arrangements and combinations ofthe various devices and parts, as well as in the details of theconstruction of the same, without departing from the scope of thepresent invention as set forth in the foregoing specification, and asdefined in the clauses of the claim which are appended thereto. Hence, I

do not limit my present invention to the exact arrangements andcombinations of the several devices and parts as described in the saidspecification, nor do I confine myself to the exact details oftheconstruction of the said parts, as illustrated in the accompanyingdrawings.

I claim 1. A mixing nozzle of the character and for the purposes statedcomprising a pair of separably connected tubular elements, one of saidelements being provided with a discharge-end, and the other elementbeing provided' with means for its attachment to a hose or the like foradmitting a fluid, into and through said connected tubular elements, aninternally and longitudinally'disposed tube within and concentric withone ofv said tubular elements, saidtube being open at both ends, one ofsaid open ends located directly at the discharge-end of said tubularelement, said tube'having its other endportion extending into andterminating in the other tubular element, said tube being adapted toreceive some of the fluid admitted into the connected tubular elements,said last-mentioned tubular element being provided in its side with anopening, an inlettube mounted in said opening, said inlettube having abent portion extending into and terminating in said internally disposedtube at a point substantially back of the discharge opening thereof forcarrying another fluid into said internally disposed tube, substantiallyas and for the purposes set forth.
